Option B is correct.

Step-by-step explanation:

We need to identify which of the following equations has exactly one solution.

We will solve each equation to find the answer

A. ax+b=ax+b

Solving and finding value of x:

ax+b=ax+b\\ax-ax=b-b\\0=0

This equation has infinite number of solutions because both sides are equal to 0

B. ax=bx+c

Solving and finding value of x:

ax=bx+c\\ax-bx=c\\x(a-b)=c\\x=\frac{c}{a-b}

This equation has exactly one solution

C. ax+b=ax+c

ax+b=ax+c\\ax-ax=c-b\\0=c-b

This equation has no solution because both sides are not equal.

So, Option B is correct.

Answer:

From <u>fourth</u> month onwards, the growth rate of f(x) is greater than that of g(x).

Step-by-step explanation:

Given:

The growth rates of both bank accounts are given as:

f(x)=3^x\\g(x)=5x+25

Now, as per question, we need to find the value of 'x' when the value of f(x)>g(x). Or,

3^x>5x+25

Now, we can do this by checking the values of 'x' by hit and trial method.

Let x=1. The inequality becomes:

3^1>5(1)+25\\3>30(False)

Let x=2. The inequality becomes:

3^2>5(2)+25\\9>35(False)

Let x=3. The inequality becomes:

3^3>5(3)+25\\27>40(False)

Let x=4. The inequality becomes:

3^4>5(4)+25\\81>45(True)

Therefore, the value of 'x' for which f(x)>g(x) is 4.

So, from the fourth month onwards, the balance in f(x) becomes greater than g(x).

The graphical solution is shown below to support the same.

From the graph, we can conclude that after the 'x' value equals 3.4, the graph of f(x) lies above of g(x). Hence, f(x)>g(x) for x>3.4
